Title
Service Finder Bookings <= 6.0 - Authenticated (Subscriber+) Privilege Escalation via change_candidate_password
Summary
The Service Finder Bookings plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 6.0. This is due to the plugin not properly validating a user's identity prior to processing a password change request. This makes it possible for authenticated attackers with subscriber access or higher to reset other users' passwords, including those of admins.

CVE-2025-5948 (GCVE-0-2025-5948)

Title
Service Finder Bookings <= 6.0 - Unauthenticated Privilege Escalation via claim_business
Summary
The Service Finder Bookings plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 6.0. This is due to the plugin not properly validating a user's identity prior to claiming a business when using the claim_business AJAX action. This makes it possible for unauthenticated attackers to login as any user including admins. Please note that subscriber privileges or brute-forcing are needed when completing the business takeover. The claim_id is needed to takeover the admin account, but brute-forcing is a practical approach to obtaining valid IDs.

CVE-2025-4855 (GCVE-0-2025-4855)

Vulnerability from cvelistv5 – Published: 2025-07-08 23:22 – Updated: 2026-04-08 17:15

Title
Support Board <= 3.8.0 - Unauthenticated Authorization Bypass due to Use of Default Secret Key
Summary
The Support Board plugin for WordPress is vulnerable to unauthorized access/modification/deletion of data due to use of hardcoded default secrets in the sb_encryption() function in all versions up to, and including, 3.8.0. This makes it possible for unauthenticated attackers to bypass authorization and execute arbitrary AJAX actions defined in the sb_ajax_execute() function. An attacker can use this vulnerability to exploit CVE-2025-4828 and various other functions unauthenticated.

CVE-2025-4796 (GCVE-0-2025-4796)

Vulnerability from cvelistv5 – Published: 2025-08-08 18:26 – Updated: 2026-04-08 17:11

Title
Eventin <= 4.0.34 - Authenticated (Contributor+) Privilege Escalation via User Email Change/Account Takeover
Summary
The Eventin plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 4.0.34. This is due to the plugin not properly validating a user's identity or capability prior to updating their details like email in the 'Eventin\Speaker\Api\SpeakerController::update_item' function. This makes it possible for unauthenticated attackers with contributor-level and above permissions to change arbitrary user's email addresses, including administrators, and leverage that to reset the user's password and gain access to their account.

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
